A New Way of Calling Taxis
Nowadays, many companies provide a new taxi service through Apps on the smart phone. They have grown quickly. An App, in fact, is a computer program working on smart phones, computers and other communication devices.
⒈
The nicest thing about this kind of Apps is that you can see where your taxi is or how long it will take to reach you on your smart phone screen. And you can also find the telephone number of the driver in the App, so you can call or send messages to the driver when you are waiting.
⒉
The App is always there 24 hours a day, 365 days a year. If you want to go somewhere, you can easily open the App at home or anywhere in the open air, then it connects you to the nearest driver. Usually it takes only between 5 and 15 minutes to get a taxi by using the App.
⒊
This way of calling taxis is popular because of its great service. You have nothing to do with a taxi company. If you are very pleased with the ride and the driver, you can give the driver a high score through the App, so the taxi drivers usually serve well. Generally speaking, it can make you feel good.
⒋
Moreover, the payment can be easily done through your bank card or Alipay. How much you need to pay depends on the country and the city that you are in. Actually discounts can be found from time to time. So calling taxis through the Apps is usually much cheaper than hailing the taxis on the road.
⒌
Also, the taxis are cleaner than normal taxis. Sometimes the drivers are not the real taxi drivers. They have their own work. They drive their cars for exchange money, so they keep their cars clean all the time. They want passengers to feel comfortable.
